Abstract (en)
[origin: EP2096502A2] An image forming apparatus includes: a plurality of photosensitive bodies disposed along a moving direction of a recording medium; a drive mechanism for driving and rotating the plurality of photosensitive bodies; a plurality of exposure units, each exposure unit being associated with a respective one of the photosensitive bodies, the each exposure unit configured to expose the respective photosensitive body; a determining unit for determining an exposure-starting phase that is a rotation phase at an exposure-starting timing with respect to one photosensitive body among the plurality of photosensitive bodies; and a varying unit for varying a exposure-starting time difference between the exposure-starting timing of the one photosensitive body and an exposure-starting timing of an other photosensitive body disposed at a downstream side of the one photosensitive body in the moving direction of the recording medium, based on the exposure-starting phase.
